Look, you're not getting what I am saying, nor apparently what everyone else he is saying. Its not that big of a deal. I understand it hurts him. Oh well. Its something that you hope doesn't happen to others, but it does. Suck it up, do better next time, thats the brakes. Sorry.
Its is not fair at all, I totally agree, but thats the way the world works. You think its any different in real life? Somebody sees a news clip about Kaizen management and implements it and gets a promotion rather than someone who didn't see the clip, people who win cases based on the leanings of a judge, and people getting jobs based on who they know...none of thse are fair, but they happen. This will not be the last time that something b.s. happens, it is just the way things work.
It still comes down to, the reason your friend is upset, is because it worked against him. It sucks man, it really does. I feel bad for him. But again, he had every opportunity. Things didn't work out for him. Hopefully he was able to get past it, but if this is the biggest injustice that happens to him, he will have had a great life.
